PC is already larger than active users on both PlayStations combined, and it didn’t used to be that way. Given the Steam Deck and what Microsoft have been saying about handhelds and their next console(s), you’re looking at a very real possibility that the next Xbox is just a PC with a different UI, like the Steam Deck.
Now we’re in philosophical territory with questions like, “What is a console?” It runs PC games, but you can navigate it with a controller. It has most console features but is malleable enough to have most PC features.
sure, it’s a spectrum. but to me the biggest defining feature of a console is being a self-contained wad of hardware, unable to be upgraded or repaired piece by piece.
